Ok. Here's the skinny: Necro pet tanking is only viable at certain times in certain areas. The necro pet is generally considered the weakest or least versatile of the three pet classes. You'll be fighting undead, of course, so you can slow them.
Necros get a few different heals. There is a line of instant-HP transfer that can be used on any friendly target (player or pet). Then the Shadowbond line, which is a slower life transfer over time, also player/pet. Then there's the pet heal, which has an annoyingly broad gap between levels 29 and 63, I think.
But, you're in luck - another tool now at your disposal is Soul Orb, which is a Direct Damage that stores the enemy HP into a stackable, potion-belt enabled, no-rent Orb. It's like nuking for heal potions. Nuke up a few stacks (of five), use them on your pet, or yourself, or a player.
Healing foci and the Theft of Life AAs, which give crits on lifetaps, will work on all the instant heals, including the Soul Orb.
For successful pet tanking, especially at the higher levels, you may have to combine a few of these options to keep the pet alive. Pre-buffing is recommended, of course. You'll still need to DoT up the mob for damage. There are also ward spells for the pet that act sort of like a Rune, which can help with harmtouching mobs. Pet tanking in general is not very effective at these levels (60+) but will work well in Charasis (Howling Stones) and some parts of Veksar. Remember to use your warrior (or possibly monk) pet instead of the rogue pet.
